Patented Aug. 18, 190s.

Application filed. March 30, 1907. Serial No. 365,578.

`To all whom it may concern:

Be it known that I, CHARLES A. MOORE, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented a new and useful Improvement in Refrigerator-Cars, ofwhich the following is a specification. y

My invention relates to improvements in and ventilated.

The primary object attained by this invention is the ventilation of'thatclass of cars above referred to.

Further objects are the maintenance of a sufliciently low temperaturewithin .the car when the outside atmosphere is warm and of a temperatureabove freezing when the outside atmosphere is below, simplicity ofconstruction, and effectiveness in use. De end- Hig in part upon theserequirements, provlde a combined ventilator, refrigerator and heater bymeans of which the air withinthe car is circulated and maintained at theproper temperature and humidity in the simplest and most direct andeflicient manner to accomplish the objectsv sought.

My invention further consists of the features, details of construction,and combinations of parts hereinafter described and claimed.

In the accom anying drawings, forming part of this specliication, Figure1 is a central longitudinal section of part of a refrigerator car, aportion of the side shown being broken away to illustrate its reinforcedconstruction; Fig. 2 is a cross sectional view of the car taken on theline X-X of Fig. 1; Fig. 3 is another cross sectional view taken on theline Y-Y of Fig. 1; Fig. 4 is a plan view of that portion of the carshown in Fig. 1, a portion of said car being taken in section on theline Z-Z` of Fig. 1; Fig. 5 is a diagrammatic plan View in section ofthe roof of one-half of the car illustrating the arrangement of the airducts inthe walls of the car; Fig. 6 is a diagrammatic side view-ofone-half of the car illustratin the arrangement of the air ducts in thewal s ofthe car; Fig. 7 is a diagram-I matic plan view of the floor ofone-half of the car illustrating the arrangement of the air ducts; Fig.8 is a diagrammatic view in section of one end of the car illustratingthe air ducts in the walls; Fig, 9 is an enlarged detail sectional viewof one of the automatic fans used in the air ducts and Fig. 10 is asectional view of Fig. 9. taken on the line A-A.

Speaking generally, the car A having licor B, sides C, ends D, andceiling or roof F is provided with an ice bunker G and a heating chamberJ. The walls, flooring, and roof of the car are made double, treble, orquadruple, with any desired number of dead air spaces 2 between theseparate portions of the" walls, which air spaces may, if desired, befilled with any suitable material which may serve to insulate theinterior of the car. The Ventilating passageway H surrounding theprovision, chamber I in the car however, is open and notiilled withmaterial of any kind and is connected with the ice bunker G and heatingchamber J.

vThe ice bunker is located substantially midway between the ends of the.car and extends horizontally along its roof and below the ceiling, itbeing understood that the drawings illustrate but a portion of the carand that the ends are of similar construction. The ice bunker consistsof a flooring 3 which is supported upon intersecting I beams 4, the endsof the transverse beams thereof being set and supported in the sidewalls of the car. apexes Vdirected upward and resting upon the strips 6above the iioor of the ice bunker serve to su port the ice. The waterdrlping from tlife ice passes from the Hoor of the bunker down the drainthrough the sides and leadlng below the floor of the car. The ends oftheice bunker have openings 8 communicating with the u per portion of thecar in the provision cham er I and are provided with horizontal slats 9spaced apart. The frame of the car adjoining the ice bunker isreinforced by the braces 10 located in the sides. It is understood thatthe ends of the bunker are of similar construction, the drawingsillustrating but one. In the roof of the car immediately above the icebunker are hatchways 11 through which ice is placed in the ice bunker.These hatchways are closed by means of Stoppers 12 and covers 13. i

The heating chamber J is located substantially midway between the endsof the car and below the floor thereof'. Its walls are suitablyinsulated in substantially the same manner as the refrigerator car. Thisheating chamber is provided with a hinged door Angle 1rons 5 with theiripes 7 extending 14 so that access can be had to the interior of,

the heating chamber for the purpose of operating the heating medium. Inthis heating chamber is laced a stove 15 which carries a supply of oil)or any suitable fuel. Air is admitted to the heater through passageways16 which arel provided with hand-operated valves 17 for regulating theamount of air supplied to said refrigerator. The gases and products ofcombustion are carried from the heater by means of the pipe 18 whichextends upward through the roofy of the car by means of branches 19. Airis admitted into the heating chamber through inlets 20 which havehand-operated valves 21 and regulates the supply of fresh air passing uthrough the heating chamber into the Venti ating passageway Hsurroundingthe provision chamber I in the car. It is obvious that heat may bcgenerated in the heating chamber by any suitable means desired, withoutdeparting i rom the principles which I have applied.

The Ventilating passageway H surrounding the rovision chamber I in thecar is constructedJ by means cfa lining 25 which is secured by partingstrips 26 to the w'alls, iiooring and ceiling of the car; These. artingstripsare disposed longitudinally in t ie path of the current of airissuing from .the heater or ice bunker and generally speaking, traverscthe roof of the car from the ice bunker towards its ends as illustratedin Fig. 5,

thence downwardly through the side and end walls as illustrated in Figs.6' .andA 8 and thence longitudinally in the iioor of the car toward theheating chamber, the arting strips in said floor being perforatedp at 27and the passageways formed by all of said strips interconnecting witheach other as shown in the drawings- In the iioor, substantially midwaybetween the ends of the car, are transverse parting strips 28 which formpassageways communicating with the top of the heating chamber and theVentilating passageway Hlsurrounding the provision chamber I. The spacesformed by the parting strips in the roof and side and end walls expandaway from .the ice bunker and vice Versa` contract away fromthe heatingchamber. The Ventilating passageway H is-.con-

nected with the provision chamber by means of the inlets 29 and 30respectively in the sides and end wallsV and near the roof, and near theiioor of the car. The inlets 29. have horizontal slats 31 which arevspaced apart and incline upwardly into the car.

In the Ventilating passageway H surrounding the provision chamber I andlo- 'cated in the spaces between the parting strips in the roof, floorand ends oibthe car are a plurality of fans 32 and 33 which increase thecurrent of air entering the ice bunker from theprovision and heatingchambers. These fans vconsist of a spring vane 35 one end of which isanchored in a block tween the partingk strips 26.

34 and its opposite end free'to vibrate by the j olting and motion ofthe car when traveling. When the Vanes of these fans are in horizontalposition the upward jolting of the'car causes them to vibrate and whenin vertical position the side jolting causes the same action. The blocks34 on which the fans are mounted are fastened in the spaces be- Anoverhead Ventilator 36 islocated in the roof of the car immediatelyabove the ice bunker, this ventilator being closed or opened by means ofa valve 37. When the valves 21 and 37 are opened, fresh air iscirculated through the car and any provisions such as fruit and othercommodities in transit are kept fresh and prevented from deteriorating.To cool the car, the lice bunker is filled .with ice. The warm -air isinjected into the top of the ice bunker by the Ventilating passageway Hsurrounding the .prow'sion chamber I, and

-the cold air from thelice bunker descends into the car through theopenings 8. When it is desired toraise the temperature ofthe car, theheater 15`is operated and the valves 21 opened. The air from the heating'charnber passes up through the Ventilating passagewayH, into `the carthrough the inlets 29 and 30 and when it is desired to increase andfreshen this circulation, the valve 37 can be openedr l j In accordancewith the patent statutes,"I have `described the rinciple of operation ofl my invention, toge't. er with the ap aratus 100 which I now considerto represent t e best embodiment thereof, but Il desire to have itunderstood that the: apparatus shown is only-,illustrative and thattheinvention can be carried out by other means and aplpliedl to uses otherthan those above set fort Havingy described my invention, what I claimas new and desire to protect by Letters Patent, isnv 1.
